From what I can gather the T-80 was never sold for export, and wasn't really favoured even inside the USSR compared to the T-64 and T-72.
Well, that definitely strikes the T-80, which was just something I named off to name a tank anyway. Not so hot on the idea of turbine power (pun intended) and much prefer working with diesels. Like Moran said, "if you understand suck-squeeze-bang-blow you can maintain [the T-55]" and they're at least something I can maintain with my industry base.
Instead of the T-72 you could go for the M-84 - it's a Yugoslavian version of the T-72 and arguably a better vehicle thanks to a more powerful engine, improved armour and electronics. The further improved M-84A / AB (export version of the A) wasn't available until 1988 though.
That's legitimately funny considering the Totally Not setting I've decided on. Didn't realize they had the full industry for tank production in-house...okay, so while the big order is for imported T-72Ms, at the same time plans are drawn up for the first Amartiyan-produced tank, and it's...the M-84. Which doesn't come into service until 1985, so it'd just be rolling off the factory floors as of my timeframe. It's fine, it gives me something to aim the government at.
Maybe this whole thing is a Hero Project, buying as many tanks as I can get while reverse-engineering the things. T-72Ms would start arriving in 1980, and while taking in 1352 tanks is a lot, over five years it's...only a rate of 22 a month. That's easily sustainable, and slow enough that I'd want to find a way to supplement it somehow, or at least not rely on guarantees from the USSR that there won't be any...delays. Around the same time in 1980, the earliest received ones get stripped down and the parts spread around the country, and factories tool up to start churning up tank parts.
That factory would only produce about 4 tanks a month, based on the 1984-1999 production run for 650 vehicles. Compared to 23 a month from the Russians, that means about 1/7 of my tank production from 1985 onward would be locally made M-84s. I've still got to replace another 1416 tanks (M60s, T-55s, Centurions) by the start of 1985, so by the time the great tank modernization ends in 1990 I'd have 220 tanks, or enough for four battalions. Just enough for a right bit of panzer elitism in the ranks!
For the IFV/APC the Warrior isn't available yet and may be too expensive. I was going to suggest looking at the Argentinian TAM and VCTP - a medium tank, APC and variants (SPG, MLRS, mortar carrier etc) but they're based on the Marder hull, and you've said that is too heavy.
I was initially thinking
Pbv 302s from Sweden as an amphibious, tracked, autocannon-armed IFV. Amphibious capability is important, even if the tanks have to make their way over bridges I'd like the recon and assorted light vehicles to handle river crossings on their own. I did look at the TAM and thought about it for a while but it just didn't feel quite right in that regard; it's not bad at all of course.
I'd consider the CVR(T) family for your reconnaissance and APC needs. It would give you two recce/light tanks (Scorpion and Scimitar), ATGM carrier (Striker), specialist APC (Spartan) and others (ARV, ambulance, CP etc) all on the same chassis. Add the FV4333 Stormer from 1982 for a larger APC - it is essentially a stretched CRV(T), retaining the same drivetrain and many other common features.
Ooooh, I knew I was missing something in the British arsenal. I kept waffling between FV432 and Warrior and completely forgot about these. Came out in 1970, 3500 vehicles produced, all very nice...and the Stormer is actually large enough to carry a squad of infantry and not just a few unorganized passengers. I think I'll roll with these for all the specialist roles. I'll reject the Spartan but take the rest, and use that Swedish IFV for most of my expansion's personnel carriers. Let's see...three years of production, I could see say...three or four battalions of Stormers being a thing. That's enough for a few brigades.
So speaking of elitism, there's definitely a hierarchy in this army even if there's some standardization going on. Brigades are still based around the 2/1 battalions standard, tanks and mechanized infantry in either order with a battalion of 2S3 Akatsiya artillery attached to each. Add in an engineer, supply, medical, and repair company, and an antitank company for the armored infantry. (Motorized infantry was just four battalions of infantry with an arty battalion and two light cav companies attached.) By 1985, here's how the army looks, at least as of right now:
Four armored brigades with T-72Ms and Stormers
Seven armored brigades with T-72Ms and Pbv 302s
Two armored brigades with M60A1s and BMP-1s
Three armored brigades with Tiran 5Shs and BMP-1s
Four armored brigades with Sho't Kal Ds and BMP-1s
Four armored infantry brigades with Pbv 302s and T-72Ms
Two armored infantry brigades with OT-64As and M60A1s
Two armored infantry brigades with OT-64As and Tiran 5Shs
Four armored infantry brigades with MT-LBs and Sho't Kal Ds
In addition, there's twelve recon battalions, eighteen AAA battalions (nine of which are M163 based and nine towed, radar-guided Bofors 40L70s), the aforementioned Corps/Theater artillery and chemical weapons delivery, and the 75,000 security forces, almost all of which are dispersed battalions or sub-units to protect various sites and facilities.
The Swedish 2A4 were leased (the lease has since expired and the tanks shipped back to Germany, where they form the majority of industry spare stock right now). Strv122 were bought later on, those were the "modified" units.
That's a thing that puzzles me. When you're leasing armored fighting vehicles, you're kind of expecting to wreck the things either from your own troops being dumb or an enemy being not so dumb. The point is to blow things up, so leasing...seems weirdly dangerous to the lessor in the potential for losing your hardware. I guess you get national guarantees of "only so much use" as part of the deal?
The reason why the T-80U wasn't all that favored in Russian service is the gas turbine, which is pretty maintenance heavy and has enormous fuel cost.
Yeah, see prior statements on diesels. It's not like we can't maintain jet engines, I mean...we have jet planes, after all, but there's a push for simplicity and reliability and my nation already ran face first into the "it gets how many yards to the gallon?" problem with Centurions before they got their diesels. I'll take the T-72, definitely; yes I know this means I'm not a fan of the M1 Abrams powerplant and no I'm not. The rest of the tank is fine for what it does, don't get me wrong, but I'd be happier without the turbine.
The nation has proof of the vulnrability of its T-55's is a start, but it is abroad and can be waved away by certain elements. Follow it up with a defeat of a unit with the Leopard 1's by T-72s - perhaps wargames with a friendly nation, or a small...misunderstanding...with an antagonistic neighbour (visability was bad, our unit didn't realise it's position had crept over the border but your tanks fired first, etc) rams home how effective the Soviet design is.
I switched the Leo 1s to M60s, but the point still stands - taking a look at how badly T-55s and Centurions were dying in the desert in '73, and a border spat that's caused by an M60 platoon getting lost and getting sniped at long range by the 125mm gun...hell, probably seeing what
the 125mm ammunition was doing even to our most heavily protected tanks at ranges it couldn't hit back at would do it. Maybe there's been a push from the military for full mechanization anyway, and it just took the results from the Yom Kippur war, the loss of one of our own brigades in a different war abroad, and a clear analysis after a border skirmish costs a few tanks unexpectedly that this new T-72 is some hot stuff.
